Quick Answer
Pneumonia is an infection in one or both lungs. Children may have a cough, fever, fast breathing, chest pain, or less energy. Babies may feed poorly or seem unusually sleepy. A clinician needs to assess suspected pneumonia. Treatment depends on the likely cause and how unwell the child is.
Severe breathing trouble, pauses in breathing, blue or gray lips, or a child who is hard to wake need emergency help.
Get Emergency Help for These Signs
- Your child is gasping, struggling for each breath, or cannot speak or feed because of breathing trouble.
- The skin pulls in deeply around the ribs or neck, or your child grunts with each breath.
- There are pauses in breathing.
- The lips, tongue, or face look blue or gray.
- Your child is very hard to wake, confused, unusually floppy, or rapidly getting worse.
Call your local emergency number. Do not wait for a home oxygen monitor to show a low reading.
A cough can be worrying when your child also has a fever and starts to breathe faster. Pneumonia is one possible cause, but other chest illnesses can look much the same. An examination helps the clinician decide what care your child needs.

What Is Pneumonia in Children?
Pneumonia is a lung infection. Inflammation and fluid can affect the small air sacs and make breathing harder. It may involve one area or several areas of the lungs.
Doctors use the term community-acquired pneumonia when the infection starts outside hospital. It can follow a cold or another breathing illness, though an earlier infection is not always clear.
Viruses and Bacteria Can Cause Pneumonia
Respiratory viruses and bacteria are common causes. A child can also have a viral infection followed by a bacterial infection. Symptoms overlap, so a cough sound or mucus colour cannot reliably show which germ is involved.
Healthy children can get pneumonia. Young babies and children with certain lung, heart, immune, or other health conditions may need closer care.
What Is Walking Pneumonia?
“Walking pneumonia” is a name often used for a milder lung infection linked to Mycoplasma pneumoniae, a type of bacterium. A child may still be fairly active despite a lasting cough.
The name does not mean the illness is always harmless. Breathing trouble or a child who is getting worse still needs assessment. Read more in our walking pneumonia guide.
Symptoms of Pneumonia in Children
Common signs include a cough, fever, fast or hard breathing, low energy, and poor appetite. Some children have chest pain when they cough or take a deep breath. Tummy pain or vomiting can occur too.
Babies may show less clear signs. Poor feeding, fewer wet nappies, unusual sleepiness, or a change in breathing can matter more than a loud cough. Fever is common, but its absence does not rule out a serious illness.
Look at Breathing While Your Child Is Calm
Watch the chest and tummy when your child is resting. Crying, running, and fever can raise the breathing rate. Breathing that stays much faster than usual at rest needs medical advice, especially with cough or fever.
Look for skin pulling in between or below the ribs, nostrils widening, head bobbing in a baby, or grunting. These can show that breathing is taking extra effort. Do not spend time counting breaths if your child is clearly struggling.
| What You Notice | Why It Matters | What to Do |
|---|---|---|
| Severe breathing effort, pauses, or blue or gray lips | These may signal a serious breathing problem. | Call your local emergency number now. |
| Hard to wake, confusion, or unusual floppiness | A major change in alertness is a danger sign. | Get emergency help. |
| Fast breathing at rest, new rib pulling, or chest pain | Your child needs an assessment of breathing and illness severity. | Seek urgent medical advice. Use emergency care if severe or worsening. |
| Poor drinking, repeated vomiting, or much less urine | Dehydration may develop and medicine may not stay down. | Seek prompt medical assessment. |
| Baby under 3 months with a temperature of 38°C or higher | Fever at this age needs immediate medical assessment. | Contact urgent medical services now, even without a strong cough. |
| Cough remains, but breathing, drinking, and energy improve | Cough can settle more slowly than other symptoms. | Follow the care plan and watch for new or worsening signs. |
When Should You Contact a Doctor?
Arrange a prompt assessment if you think your child has pneumonia. Do not try to confirm it from an online symptom list. Seek help sooner for a young baby or a child with a serious underlying condition.
During treatment, contact the clinician if breathing becomes harder, drinking falls, fever returns, or your child seems more unwell. You do not need to wait for a planned review when symptoms worsen.
Can Asthma or Bronchiolitis Look Similar?
Yes. Asthma, bronchiolitis, and pneumonia can all cause cough or breathing changes. A child may also have more than one problem at the same time.
If your child has asthma, follow their written asthma plan while seeking help for concerning symptoms. An inhaler does not treat the lung infection itself. See our guides to childhood asthma and bronchiolitis in babies.
How Is Pneumonia Diagnosed?
The clinician asks about symptoms, checks breathing, and listens to the chest. They also assess hydration, alertness, and oxygen levels when needed. Tell them about existing conditions, medicine allergies, and recent treatment.
Does Every Child Need a Chest X-Ray?
No. Routine chest X-rays are often unnecessary for mild pneumonia managed at home. Imaging is more useful when illness is severe, complications are suspected, or the child does not improve as expected.
An X-ray cannot always separate viral from bacterial pneumonia. Blood tests and swabs are also chosen for a reason rather than used for every child. The clinician combines the results with the examination.
What About a Home Oxygen Monitor?
A pulse oximeter estimates blood oxygen. Readings can be affected by movement, cold skin, poor circulation, device fit, and skin pigmentation. Some consumer devices are not suitable for checking a small child.
A reassuring number does not cancel out visible breathing trouble or reduced alertness. If a clinician asks you to use a monitor, get clear instructions on the device and when to seek help.
How Is Pneumonia Treated?
Treatment depends on age, illness severity, likely cause, and health history. Some children can recover at home with a clear care plan. Others need hospital support.
Antibiotics for Suspected Bacterial Pneumonia
Antibiotics treat bacteria, not viruses. However, the cause is not always clear at the first visit. A clinician may prescribe an antibiotic when bacterial infection is suspected or cannot be safely ruled out.
Give the prescribed dose for the prescribed number of days. Course lengths differ between children and local guidelines. Do not stop early, extend treatment, or use leftover medicine without advice.
Ask the pharmacist what to do if a dose is missed or vomited. Do not automatically repeat a dose, since the right action depends on the medicine and timing.
Treatment for Mycoplasma Pneumonia
Mycoplasma lacks the cell wall that some antibiotics target. This means medicines such as penicillin do not work against it. Clinicians choose an appropriate antibiotic when treating pneumonia caused by this germ.
Resistance can occur. If your child is not improving, return for review rather than changing antibiotics yourself.
Care for Viral Pneumonia
Care often focuses on fluids, rest, symptom relief, and watching breathing. Some viral infections have specific treatments for eligible children. The clinician decides whether these are needed.
A viral diagnosis does not mean breathing trouble is safe to manage at home. The child's condition matters as well as the cause.
When Hospital Care Is Needed
A child may need admission for low oxygen, severe breathing effort, dehydration, inability to take medicine, or a complication. Very young age and underlying illness can also affect the decision.
Hospital treatment may include oxygen, fluids, antibiotics, and close monitoring. Some children need more breathing support. Ask the team what must improve before your child can safely go home.
Safe Home Care After Diagnosis
Home care is appropriate when a clinician has assessed your child and said it is safe. Keep the treatment instructions and contact details easy to find.
Offer Fluids Often
Small, frequent drinks may be easier than a full cup. Continue breast milk or normal-strength formula for babies. Do not dilute formula to add water.
Watch for a dry mouth, fewer wet nappies or toilet trips, and unusual tiredness. Poor appetite is common for a short time, but poor drinking needs more attention. Do not force food or drinks when your child is struggling to breathe.
Use Pain and Fever Medicine Safely
Ask which medicine and dose are suitable for your child's age and weight. Product strengths vary. Use the supplied measuring device and record doses to help prevent double dosing.
Do not give aspirin unless a specialist has prescribed it. Avoid ibuprofen when a child is dehydrated. Age rules vary by country, so check the local label and ask a clinician before giving it to a young infant.
Avoid Cough Suppressants and Hot Steam
Cough helps clear mucus. Do not give cough suppressants for pneumonia unless the treating clinician specifically advises them. They do not treat the infection.
Do not use bowls of boiling water or steam tents. They can cause burns. Essential oils and homemade mixtures should not go into a nebulizer.
Keep Rest and Sleep Safe
Let your child rest and return to quiet play as energy improves. Keep smoke and vape aerosol away from the home and car.
Babies should sleep on their backs on a firm, flat sleep surface. Do not raise the mattress or add pillows to help a baby breathe. If a baby cannot breathe comfortably in a safe sleep space, seek medical advice rather than changing the sleep setup.
Recovery: What Should Improve and When?
Recovery is gradual. Many children begin to improve within a few days of treatment. NICE advises that fever and breathing difficulty should usually resolve within about 3 to 4 days, while a cough may fade over several weeks.
These are guides, not a reason to wait through worsening symptoms. Contact the clinician if improvement has not started within 3 days, or earlier if the care plan sets a shorter review time.
| Area to Watch | A Reassuring Trend | Reason for Another Check |
|---|---|---|
| Breathing | Less effort and a more comfortable rate at rest. | New rib pulling, grunting, faster breathing, or breathlessness. |
| Fever | Temperature settles as the child improves. | Fever persists without improvement or returns after settling. |
| Drinking | More regular drinks and urine output. | Repeated vomiting, very poor intake, or much less urine. |
| Energy | Gradual return to talking, playing, and normal responses. | Increasing sleepiness, weakness, or difficulty waking. |
| Cough | Slowly becomes less frequent while the child otherwise improves. | Worsening cough with new fever, chest pain, or breathing trouble. |
Does a Lingering Cough Mean Treatment Failed?
Not always. Cough can outlast the fever because the airways take time to settle. What matters is the overall trend. A child who is breathing comfortably, drinking well, and gaining energy is different from one who is getting more unwell.
Ask for review if the cough is not settling as expected or lasts beyond the recovery period discussed with the clinician.
Is Another Chest X-Ray Needed?
A routine follow-up X-ray is generally unnecessary after uncomplicated pneumonia that resolves normally. Ongoing symptoms, repeated infection in the same lung area, or concern about another condition may lead to further tests.
Complications and Repeat Pneumonia
Some children develop fluid around the lung. Infected fluid is called empyema. Persistent fever, worsening pain, or poor recovery can lead the team to check for these problems.
Small, uncomplicated fluid collections may be monitored with treatment. Larger or infected collections may need drainage. Current IDSA/PIDS guidance addresses these hospital decisions; parents should not try to judge the need for drainage from symptoms alone.
Repeated confirmed pneumonia also deserves a discussion. Tell the clinician about poor growth, a long-lasting wet cough, choking with feeds, or other severe infections. These details can help decide whether a specialist assessment is needed.
Prevention and Returning to School
Keep vaccines current under your country's schedule. Vaccines against pneumococcal disease and other infections can reduce some causes of pneumonia. Ask about catch-up doses and any extra protection needed for your child's health conditions.
Handwashing, covering coughs, better indoor air, and avoiding smoke help reduce exposure. No food, supplement, or home remedy guarantees that a child will not get pneumonia.
When Can a Child Return to School?
Return when your child is well enough to take part, breathing comfortably, and meeting the school's fever and infection rules. The germ involved may affect the advice.
Restart sports gradually. Seek advice if activity causes chest pain, dizziness, unusual breathlessness, or marked fatigue. Children who had severe pneumonia may need a specific return plan.
Frequently Asked Questions
What are the first signs of pneumonia in children?
Common signs include cough, fever, fast or hard breathing, and low energy. Babies may feed poorly or seem unusually sleepy.
Can a child have pneumonia without a fever?
Yes. Fever is common but is not always present. Concerning breathing changes or reduced alertness still need medical assessment.
Does every child with pneumonia need antibiotics?
No, but a clinician may prescribe them when bacterial pneumonia is suspected or cannot be ruled out. Antibiotics do not treat viruses.
Does every child need a chest X-ray?
No. Mild pneumonia can often be assessed without routine imaging. Severe illness, suspected complications, or poor recovery may require tests.
How long should my child take antibiotics?
Follow the exact course prescribed for your child. Do not shorten, extend, or change it without advice from the treating clinician.
When should I seek emergency help?
Get emergency help for severe breathing trouble, pauses in breathing, blue or gray lips, confusion, or a child who is very hard to wake.
Can walking pneumonia become serious?
Yes. It is often milder, but worsening breathing, poor drinking, or marked weakness still needs prompt medical assessment.
Can a cough last after pneumonia treatment?
Yes. Cough may improve slowly over several weeks. New fever, worsening breathing, or a child who becomes more unwell needs another check.
Should I give cough medicine for pneumonia?
Do not give cough suppressants unless the treating clinician specifically advises them. They do not treat the lung infection.
Can a home oxygen monitor rule out serious pneumonia?
No. Readings can be inaccurate. A normal-looking number must not delay help for breathing trouble or reduced alertness.
